MECHANISM FOR FEEDING BLANKS- Specification of Letters Patent.

Patented June 11, 1907.

Application filed February 10,1906. Serial No. 300,522.

In (LU whom it may concern:

Be it known that I, CHRISTIAN DANCEL, a l

citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Mechanism for Feeding Blanks, of which the following is a specificatIon.

This invention relates to mechanism for feeding blanks for skiving or trimming and the like. 7

An object of the invention is to accurately feed or cause the blank to be alined or set for proper feeding so that they will be trimmed as required.

This invention resides in novel features of construction set forth in the following specification and claim and illustrated in the annexed drawing, in which:

Figure 1 is a plan View of a machine embodying this invention. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a section along :0 0c Fig. 1. Fig. 4 is a rear view of Fig. 1. Fig. 5 shows boxes or bearings for a die and pres- Fig. 6 shows a gage piece. Fig. 7 shows a modification.

In this drawing is shown a table a for sup- A hopper is shown having a front wall 0 and side walls (I. The front Wall is spaced a certain distance above the table to allow the bottom blank to be fed or pass thereunder. The side walls are adjustable so that they can be setfor varigus sizes of blanks. Screws or bolts 0 passing through slots in the hopper sides can adjustably secure the same to the size of blanks to be treated. These screws or fastenings (2 can enter threads in the table.

The feed or eject-or for moving the under blank out of the pile comprises a slidef actuated by suitable means as for example link 9 and eccentric or crank pin h. The slide carries afinger or rather a pair of fingersi pivoted at k to such slide. The fingers are weighted or made to normally stand upright or in position when moving forward to feed or slide the lower blank forward. The finger weights are shown at m, and when moving a blank forward the finger is held steady or prevented from yielding by its finger or stop n striking against the slide. On the return the fingers can yield to slip or pass idly by or under the pile or work. The table being suitably slotted the fingers in this forward stroke being held against retrograde movement or swing will reach to and feed a blank.

A pressure or gage piece is shown at 0. This gage 6 might be a roller as seen at 0 Fig. 7 or a non rotary piece 0 Fig. 6. A spring or springs 79 causes this gage piece to press or bear yieldingly onto the blank. This gage piece 0 is shown concave and this construction has been found to straighten or aline the blanks as they are fed. If a blank in the hopper should be awry or out of position'it will be straightened or positioned. The fingers act against such blank and as it moves forward the outer portion of such blank contacts with the outer or thicker portions of the concave while the central portion of the blank is still out of contact with the central or thin portion of the gage. The blank is then brought to position to come squarely to the trimming mechanism.

The trimming mechanism comprises a knife 9 which can be adjusted and fixed in position by suitable screws 1-. The die roller 8 and feed roller t are suitably driven and bring the blank to the trimmer or knife. A spring or springs 2 tend to separate the rollers or their boxes and screws 3 can be made to hold down the die roller or its shaft boxes. The feed roller boxes are carried by a stem 4 threaded for engagement by nuts 5. Spring 6 tends to lift or hold the feed roller to the die roller. By adjusting the nut upwardly on the stem I, the springs will be compressed, thereby drawing the feed roller away from the other roller. WVhen the nuts are adjusted in an opposite direction, the springs expand thereby moving the feed roller against the other roller.

That I claim as my invention and desire to secure by Letters Patent, is:

In a machine for feeding blanks, the combination with a supporting table and a spaced wall between which and the table one blank at a time can pass, of a die roller and feed roller for the blanks, and a gage piece in advance of the rollers, said gage piece being of concave shape so as to leave a space between the same and the table, saidspace gradually diminished from the center outward, and a spring for yieldingly holding the gage piece in position.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
